The Sun Hydraulics NCEBOAN (NCEBOAN) is a needle valve with a reverse flow check, designed to provide precise flow regulation in hydraulic systems. This component serves as a fully adjustable orifice, allowing for infinite adjustment from fully closed to the maximum orifice diameter. It features an integral high-capacity check valve that ensures unrestricted flow from port 2 to port 1. Notably, this model is not pressure compensated, meaning that the fixed orifice size will regulate flow based on the square root of the pressure differential across ports 1 and 2. The NCEBOAN incorporates a balanced adjustment mechanism for ease of use even under high pressures and employs a sharp-edged orifice design to minimize flow variations due to viscosity changes. The cartridge's floating style construction minimizes the risk of internal parts binding due to excessive installation torque or machining variations. It is configured with EPDM seals, making it suitable for systems using phosphate ester fluids while being incompatible with petroleum-based fluids. The NCEBOAN fits into a T-5A cavity and is part of Series 2, offering a capacity of 12 gpm (45 L/min) with a maximum operating pressure of 5000 psi (350 bar). The valve has minimal leakage at standard conditions and allows for up to five counterclockwise turns from fully closed to open. Installation requires specific torque settings for both the valve and locknut, ensuring secure placement within hydraulic systems. With its robust design and versatile functionality, this needle valve is ideal for applications requiring precise flow control without pressure compensation. Its compatibility with specific fluid types and resistance to internal binding make it a reliable component in demanding environments.

Needle valves with reverse-flow check are fully adjustable orifices used to regulate flow. They are infinitely adjustable from fully closed up to the maximum orifice diameter. An integral high-capacity check valve provides unrestricted flow from port 2 to port 1. They are not pressure compensated.
- All 2-port flow control cartridges are physically and functionally interchangeable (i.e. same flow path, same cavity for a given frame size). However, cartridge extension dimensions from the mounting surface may vary.
- Because needle valves are non-compensating devices, the fixed orifice size will regulate flow through the valve in proportion to the square root of the pressure differential across ports 1 and 2.
- A balanced adjustment mechanism allows for easy adjustment even at high pressures.
- The sharp-edged orifice design minimizes flow variations due to viscosity changes.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
